The Brailliant BI 20X is a portable, 20-cell refreshable braille display built by HumanWare, designed for users who need a lightweight yet capable braille device that works both as a standalone notetaker and as a display for computers, phones, or tablets. It combines a Perkins-style braille keyboard, cursor-routing keys, and a responsive braille display with a suite of onboard applications, making it useful not only for reading and writing braille but also for note-taking, file management, and access to digital content — all while remaining compact enough for travel or daily carry.
